The following is taken from Agfa's technical sheet:
Rodinal (1+100)
Film Type Time Contrast Speeds
______________________________________
APX 25 15 min 0.55 ISO 16
20 min 0.60 ISO 20
APX 100 15 min 0.45 ISO 64
20 min 0.50 ISO 100
Neopan 400 15 min 0.55 ISO 200
20 min 0.65 ISO 250
Neopan 1600 15 min 0.60 ISO 250
20 min 0.70 ISO 400
Ilford FP4+ 15 min 0.45 ISO 64
20 min 0.50 ISO 125
Delta 400 15 min 0.50 ISO 125
20 min 0.60 ISO 160
Ilford HP5+ 15 min 0.45 ISO 100
20 min 0.50 ISO 160
Kodak Tri-X 15 min 0.50 ISO 250
20 min 0.65 ISO 400
T-Max 100 15 min 0.50 ISO 50
20 min 0.60 ISO 64
T-Max 400 15 min 0.50 ISO 200
20 min 0.65 ISO 250
Agitation: continuous in the first minute, then agitate or tilt every 30
seconds
Standard contrast = 0.65
I can't vouch for many of these, but Tri-X developed for 20 mins is superb.
Very sharp, full film speed, normal contrast, fine grain. Don't
over-agitate - just a gentle tilt over and back once each 30 secs. T-Max 100
for 20 mins is also superb - virtually grain-free.
Hope this is helpful,
Richard
